Abstract
The utility model provides a stable output gear shaft, which comprises a gear shaft body, wherein one side of the gear shaft body is provided with a connecting hole, and the wall of the connecting hole is provided with a key slot for connecting with an output shaft of a gear motor; the other side of the gear shaft body is provided with a connecting shaft for installing a bearing or a bearing with a seat. The connecting shaft is arranged on the frame through the gear or the gear with the seat, so that one side of the gear shaft body is fixed on the output shaft, and the other side of the gear shaft body is supported, thereby not only improving the running stability of the gear shaft body, but also avoiding thickening the gear shaft body, and further reducing the cost.
Description
Technical Field
The utility model relates to the technical field of transmission, in particular to a stable output gear shaft.
Background
In gear transmission, a driving gear and a driven gear which are meshed are generally arranged. The driving gear is arranged on an output shaft of the gear motor and rotates along with the gear motor.
When the load is large, the driving gear is easily damaged due to the phenomenon of unstable rotation caused by insufficient strength. To solve this problem, the drive gear is generally thickened. Thus, the length of the output shaft is limited, and the driving gear cannot be thickened limitlessly; and the thickening driving gear can also lead to the cost to improve greatly.
Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.
Disclosure of Invention
In order to solve the technical problems in the background technology, the utility model discloses a stable output gear shaft.
The utility model provides a stable output gear shaft, which comprises a gear shaft body, wherein one side of the gear shaft body is provided with a connecting hole, and the wall of the connecting hole is provided with a key slot for connecting with an output shaft of a gear motor;
the other side of the gear shaft body is provided with a connecting shaft for installing a bearing or a bearing with a seat.
The connecting shaft is arranged on the frame through the gear or the gear with the seat, so that one side of the gear shaft body is fixed on the output shaft, and the other side of the gear shaft body is supported, thereby not only improving the running stability of the gear shaft body, but also avoiding thickening the gear shaft body, and further reducing the cost.
When the gear shaft body needs to drive two parts to run simultaneously and the synchronism requirement of the parts is high, the further improvement is as follows: the end part of the connecting shaft is also provided with a transmission shaft. Thus, one part is connected to the driven gear and the other part is connected to the transmission shaft, which is more synchronous.
The key groove is only stressed on the side wall which is consistent with the rotation direction of the output shaft, and the traditional key groove is symmetrically arranged relative to the connecting hole, so that the stressed side wall part of the key groove has thinner wall thickness and is easy to damage, the problem is further improved and solved, and the key groove is particularly eccentrically arranged relative to the connecting hole; the thicker part of the key groove is in the same direction with the rotation direction of the output shaft. Thus, the wall thickness of the stressed side wall part of the key groove is increased, so that the strength is improved, and the key groove is not easy to damage.
The area of force of keyway directly influences the life of gear shaft body, based on this, further improvement lies in: the key grooves are formed in two rotationally symmetrical ways. Therefore, the stress area of the gear shaft body is increased, and the stress is uniform, so that the service life of the gear shaft body is prolonged.
Drawings
The utility model will be further described with reference to the drawings and examples.
FIG. 1 is a front view of the present utility model;
FIG. 2 is a cross-sectional view of A-A of FIG. 1;
in the figure: 1. a gear shaft body; 2. a connection hole; 3. a key slot; 4. a connecting shaft; 5. a transmission shaft; 6. a main body; 7. and (5) clamping the shaft.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Embodiment one:
as shown in fig. 1 and 2, the present utility model is a stable output gear shaft including a gear shaft body 1. The gear shaft body 1 comprises a circular main body 6, and the outer side surface of the main body is provided with gear teeth.
One side integrated into one piece of main part 6 is connected with joint axle 7, is equipped with the connecting hole 2 of axial arrangement in the joint axle 7, and keyway 3 has been seted up to connecting hole 2 pore wall for connect gear motor's output shaft.
The other side of the main body 6 is integrally connected with a connecting shaft 4 for installing a bearing or a bearing with a seat.
The connecting shaft 4 is arranged on the frame through a bearing or a bearing with a seat, so that one side of the gear shaft body 1 is fixed on the output shaft, and the other side is supported, thereby not only improving the running stability of the gear shaft body 1, but also avoiding thickening the gear shaft body 1, and further reducing the cost.
Embodiment two:
the difference from the first embodiment is that: the end of the connecting shaft 4 is also provided with a transmission shaft 5. Thus, one part is connected to the driven gear which engages the gear shaft body 1, the other part is connected to the drive shaft 5, and the running synchronism of the two parts is higher.
Embodiment III:
compared with the embodiment, the difference is that: since the key groove 3 only has the side wall stress consistent with the rotation direction of the output shaft, and the traditional key groove 3 is symmetrically arranged relative to the connecting hole 2, the wall thickness of the side wall part of the key groove 3 which is stressed is thinner and is easy to damage, the key groove is designed as follows: the key slot 3 is eccentrically arranged relative to the connecting hole 2; the thicker part of the key groove 3 is in the same direction with the rotation direction of the output shaft. In this way, the wall thickness of the stressed side wall part of the key groove 3 is increased, so that the strength is improved, and the key groove is not easy to damage.
Embodiment four:
compared with the three phases of the embodiment, the difference is that: as shown in fig. 1, the key grooves 3 are provided in two rotationally symmetrical ways. Thus, the stress area of the gear shaft body 1 is increased, and the stress is uniform, so that the service life of the gear shaft body 1 is prolonged.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
